Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is applied.
Gather necessary tools, including jack stands, socket set, and a torque wrench.

2. Inspect and Replace Wheel Bearings

Sub-steps:
1. Lift the front or rear of the vehicle using a jack and secure with jack stands.
2. Remove the wheel by loosening the lug nuts with a socket set.
3. Inspect the wheel bearing for any signs of damage or excessive play.
4. If necessary, remove the hub assembly to access the bearings.
5. Replace the wheel bearing with a new one, applying grease as needed.
6. Reassemble the hub and wheel, ensuring lug nuts are torqued to manufacturer specifications (typically 76 ft-lbs for a Camry).

3. Inspect and Replace Serpentine Belt

Sub-steps:
1. Open the hood and locate the serpentine belt routing diagram.
2. Release tension on the belt using a serpentine belt tool or ratchet.
3. Remove the belt and inspect for cracks or wear.
4. Install a new belt, ensuring proper alignment with pulleys.
5. Reapply tension to the belt and verify it is securely in place.

4. Check Transmission Fluid

Sub-steps:
1. Start the engine and let it warm up to operating temperature.
2. With the vehicle in park, check the transmission fluid level using the dipstick.
3. If the fluid is low, add the appropriate type of transmission fluid (Toyota WS fluid).
4. Inspect the fluid condition; if it’s dark or has a burnt smell, consider a transmission fluid change.
